Abstract: Le moteur comprend plusieurs paires de pistons (PA, PA'), les deux pistons de chaque paire agissant a l'unisson et les paires etant disposees parallelement entre elles et lesdits pistons etant egalement positionnes parallelement et suivant un cercle autour de l'arbre moteur (1) qui possede un nez de came (3) situe sur une partie appropriee de l'arbre moteur et encerclant ce dernier. Dans une modification preferee, le bossage ou nez de came (3) possede des surfaces opposees ayant des elevations et des depressions ou, en d'autres termes, des surfaces sinusoidales qui sont en contact avec des paires de paliers (6) attachees aux bielles de connexion, ces paliers etant sur les cotes opposes du nez de came et etant entraines une fois dans un sens par l'un des deux pistons de chaque paire puis une autre fois dans le sens oppose par l'autre piston de cette paire, les deux pistons de cette paire etant relies entre eux par la meme bielle (4, 5) portant les paliers (6) qui s'appuient contre le nez de came (3). La pression exercee d'abord par un palier puis par le palier oppose, de concert avec des poussees identiques provenant d'autres paires de paliers et de pistons, donne comme resultat une rotation constante, reguliere de l'arbre (1) sur son axe lineaire. L'action des pistons et des paliers est prevue et synchronisee de sorte que la pression contre la surface du nez de came exerce des forces vectorielles contre la surface courbe du bossage de came pour effectuer la rotation de l'arbre moteur. Les pistons peuvent etre entraines par des combustibles, tels que l'essence, le fuel pour diesel, etc., et peuvent egalement etre adaptes pour fonctionner a la vapeur. Dans une autre modification, les surfaces sinusoidales se trouvent sur les cotes d'une rainure (40) taillee dans la surface annulaire (41) du nez ou bossage de came (3). En apportant des changements appropries, ce moteur peut fonctionner comme un compresseur.

Abstract: A process for controlling an industrial robot in which most data for controlling the robot can be supplied using a preset process without moving the robot and only data for regions in which very precise control is required need be prepared by actually moving the robot. A programming unit is provided separate from but connectable to a robot control unit. The programming unit is used to compile and transfer completed programs to the robot control unit for controlling the movements of the robot. To program the robot control unit, the programming unit and robot control unit are connected as an on-line system. Then, data describing a desired path of movement is inputted to the programming unit as a series of coordinates in Cartesian form. In regions where very precise control is required, the coordinates describing the desired path of movement are corrected using small corrective motions of the robot. The inputted data and the corrected coordinates are displayed.

Abstract: A signal analysing circuit for a periodically occurring signal, supplied by, for example, a video signal source (VSS). The circuit comprises a store (M) having separate store locations (M), which are associated with corresponding regions arranged in rows and columns on picture display of the periodically occurring video signal. In addition, a time signal generator (TG) is provided for the synchronous control of the video signal source (VSS) and the store (M). For filling in a simple manner, without disturbance, the store locations (M) with the mean value of the video signal take per accurately determined region, the output of the signal source (VSS) is coupled via an analog-to-digital converter (A/D) to counting inputs of a number of counters (BC1 to BC7) which number is equal to the number of regions per row, the counters being operative sequentially and periodically. Each counter (BC1 to BC7) is followed by a buffer register (BR1 to BR7) for taking over the counting information in the line blanking period at the end of the last signal period in the row of regions, whereafter the counter (BC) is reset. The buffer register (BR) is followed by the store (M) with the separate store locations (M), which are filled with the previous counting information during the next counting operation.

Abstract: Apparatus and method for mass flow measurement including means (25) for rotationally oscillating a substantially curved, preferably U-shaped conduit (14), solidly mounted in a cantilevered manner at the open ends of the legs (18, 20), and equipped with sensors (33, 33', 34, 34') which measure acceleration, velocity or position of each side leg (18, 20) of the conduit (14). The sensors (33, 33') are preferably velocity sensors, being each a magnet (42) and a coil (45). The coil (45) is translated in the uniform portion of the magnetic flux field, and the sensors (33, 33') produce analogue signal output which accurately correspond to the motion of the adjacent leg (18,20). In the event of flow through the conduit (14), a change from coincidence in the time relationship of the two sensor signals relative to the divergent oscillations of each side of the conduit (14) caused by mass flow is measured in both directions of oscillation. Mass flow is determined as a function of such time separation of the signals.
